UNITED STATES PATENT OFFICE.

WILLIAM R. IVILCOX, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR 0F ONE- HALF TOJOHN GERNERT, OF SAME PLACE.

HOB-NAIL.

SPECIFICATION forming part of Letters Patent No. 415,181, dated November12, 1889. Application filed July 13, 1889. Serial No.`3l7,646. (Nomodel.)

To @ZZ whom, t may concern:

Be it known that I, WILLIAM R. WILCOX, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovementJ in Hob-Nails; and I do hereby declare the following to be afull, clear, and exact description thereof.

My invention relates to an improvement in hob-nails; and it consists inmaking the nail in two parts-viz., head and tang.

To enable others skilled in the art with whichA my invention is mostnearly connect-ed to make and use it, I will proceed to describe themanner of constructing it.

In the accompanying drawings, which form part of my specification,Figure l is a sectional view of the head or hob portion with a straightOpening through it for receiving the nail. Fig. 2 is the same with atapered open- Fig. 3 is the same with the opening partially straight andpartially tapered. Fig. 4 is a perspective view of the head or hob andthe tang joined together. Fig. 5 is a crosssection of the same. Fig. Gis a section of the hob portion with the outer face countersunk, so thatwhen the tang is inserted the head of the tang will be flush with theouter face of the hob. Fig. 7 is a view of a tang or nail to be insertedin the opening in the hob. f

Reference being had to the drawings and the letters thereon, A indicatesa supplemental head or hob of the naihwhich is provided with an apertureB, through which the nail passes, and said aperture may be of anydesired form, several modified constructions being shown in the severalfigures on the drawings. The

head A may also be provided with a recess or countersink E for thereception of an enlarged or fiattened head (not shown) on the nail D. Onthe inner surface of the supplemental head are outwardly-inclinedprojections or wings C, which embed themselves in the leather when thenail and the supplemental head are driven into the sole or heel of ashoe, and assist in holding the nail and the supplemental head inposition on a shoe by reason of the Outer inclined surface of theprojection being forced into and under the grain of the leather.

D indicates the nail proper or body portion, which is provided with anenlargement or head at one end formed integral therewith, which headcorresponds in shape with the shape or configuration of the aperture Bin the supplemental head A, and whenv driven through said aperture andinto a boot or shoe sole the Outer surface or end of the head on thenail D is flush with the outer or wearing surface of the supplementalhead A. The body portion of the nai-l presents a plain smooth surface,and is slightly tapered at its driving or entering end.

Having thus fully described my invention, what I claim is- As an articleof manufacture, a hob-nail having a supplemental head separate from thenail and provided with an aperture through said head to receive the headof the nail, and outwardly-inclined projections on the inner surfacethereof to enter and embed themselves in a shoe-sole, and a fiat outerwearing-surface, and a nail having a head integral therewithcorresponding in form with and to be driven through the aperture in saidsupplemental head, substantially as described.

In testimony whereof I have hereunto set my hand this 4th day of June,A. D. 1889.

W. R. VVILCOX.
